What is the value of x????

AlekseyPX

In a 45 · 45 · 90 triangle, the hypotenuse is √2 · legs, because a 45 · 45 · 90 triangle is isosceles, so the legs are the same length. So, we have 3√2 · √2 = 6, so the hypotenuse is 6.

Find the value of 7 Y if 3 bracket Y - 1 bracket is equal 21

lawyer [7]

Answer:

$7y = 56$

Step-by-step explanation:

$3(y - 1) = 21$

Divide 3 on both sides:

$y - 1 = 7$

Add 1 to both sides:

$y = 8$

Multiply by 7 on both sides:

$7y = 56$

During a scuba dive, Lainey descended to a point 20 feet below the ocean surface.She countined her descent at a rate of 20 feet

lorasvet [3.4K]

Answer:

$20 + 20x \leq 100$

Step-by-step explanation:

Let x be the number of minutes she can continue, since she's already 20 feet below the ocean surface and is diving at the rate of 20 ft/minute, her depth with respect to x would be

20 + 20x

But she doesn't want to reach more than 100 feet below the surface

$20 + 20x \leq 100$
